Specific markers for diseases associated with protein aggregate depositions are of great interest. Here we report the use of conjugated polyelectrolytes as conformation-sensitive optical probes for histological labeling of amyloid deposits in ex vivo tissue samples-amyloid light chains in primary systemic amyloidosis, islet amyloid polypeptide in human(More)
PURPOSE The aims of this study were to assess changes in the microhardness and surface roughness of a dual-cured composite resin cement after water storage for different periods of time. MATERIALS AND METHODS Sixty specimens were divided into four groups comprising high- and low-viscosity cement specimens stored either dry or in water for 1 to 60 days.(More)
The shipping sector is today facing numerous challenges. Fuel prices are expected to increase in the medium-long term, and a sharp turn in environmental regulations will require several companies to switch to more expensive distillate fuels. In this context, passenger ships represent a small but increasing share of the industry. The complexity of the energy(More)
In recent years, the shipping industry has faced an increasing number of challenges in terms of fluctuating fuel prices, stricter environmental regulations, and concerns about global warming. In this situation, passenger volumes on cruise ships have increased from around 4 million to 13 million from 1990 to 2008 and keep growing today. A small cruise ship(More)
Waste heat recovery systems for power generation are gaining interest among the marine transport sector as a solution to accomplish the upcoming more restrictive regulations on emissions, and to reduce the total fuel consumption. In this paper we evaluate how a waste heat recovery system based on a regenerative organic Rankine cycle (rORC) could improve the(More)
Minimax Optimization of Two-Dimensional Focused Nonuniformly Spaced Arrays Recently there has been interest in applying the results of digital filter design theory to the optimization of the beam forming pattern of antenna arrays. The techniques employed usually involve minimax criteria for side lobe suppression. Certain applications require focused(More)
